Research is the central focus of the AE graduate program, but a growing number of undergraduates are also engaging in specialized research, arranged via special permit. The School's research efforts are organized around six aerospace disciplines, listed below. From this starting point, students pursue research that is richly multi-disciplinary, often resulting in collaborations outside the School and the Institute. Whatever their specific research focus, each graduate student is expected to master basic, experimental, theoretical, and analytical research techniques. Select undergraduates are invited to participate in research projects.
